The Smith-9th Street station has officially opened its doors, or at least its turnstiles again. After almost two years of renovations the F and G trains are once again stopping in Carroll Gardens.

This station, the tallest subway station in the world at 88 feet, presented some challenges to the first-ever rehabilitation of the historic stop,” according to the MTA.

“This has been a long and complicated project, and the community has demonstrated tremendous patience throughout, and for that we are grateful,” said acting New York City Transit President Carmen Bianco. He called the rebuilding a “ongoing effort.”

“We will never be in a position where we can step back and say it’s done,” he said.

When the station closed in 2010, it accounted for 4,763 fares per day. Of the 421 stations in the subway system, it ranked 286 overall and 93 out of 157 in Brooklyn.

The project cost roughly $32 million and is part of a $389 million project to rehabilitate the entire Culver Viaduct. This newly renovated station features a new control house, customer information center and covered waiting areas.

The escalators were also refurbished and the station’s structural steel and concrete elements where either repaired of replaced.

Not only is the height of the structure unique, the walls are one of a kind also. Artist Alyson Shotz was commissioned to create a series of artworks for the station that maintain a theme of maritime history.

The station opened on October 7, 1933, and was one of the two original IND system stations conducted above ground.

“This station was sorely missed by residents and business of Red Hook, Carroll Gardens and Gowanus for the two years that it was closed,” said Borough President Marty Markowitz. “Now that service is resuming, commute times for the 1.5 million people each year who use this station will be significantly shorter.”
